I think sync of contacts is one of the biggest questions here but we are still missing actual described solutions by Ritlabs online in Help for the most used email address domains.
I'm using The Bat 7.4 with multiple @outlook.com and @gmail.com accounts. All are defined as IMAP accounts.
I'm also using an iPhone (iOS 10.2) and also all mail accounts are defined.
I want to sync all contacts accross the devices (but not between the accounts of course - if possible). This could be done preferred via outlook.com or gmail.com account (I could manage them online) - but maybe also via iCloud.com website contacts.
What is the best solution to keep them sync or shortest & best compatible steps if export & import is required?
What must I do and how to config The Bat 7.4?
Come on - in 4 days we have 2017 ... and no easy solution?
